I am interested in the physics of Earth systems. In particular, my research has focused on the fluid dynamics and solid mechanics of ice as an Earth material. I use ice-penetrating radar to survey the ice sheets, their geometry, flow, properties, and the associated implications for sea-level rise. I also have growing interests in planetary ice and planetary analogs on Earth. I believe in and try to practice open science, with free access to data, code, and manuscripts.

Research Interests
Ice Temperature
Heat transfer, ice viscosity, and radar attenuation.
Crystal Fabric
Ice crystal anisotropy and radar polarimetry.
Planetary
Extraterrestrial ice and analogs on Earth
Geophysical Tools
Instrument design and software for radar processing.
Alpine Glaciology
Mountain glacier mass balance and glacier dynamics.
Drilling in Ice
Thermal drilling in theory and in practice.
Teaching
I enjoy teaching from Jupyter Notebooks. I use Binder, so each of the links to the right takes you to a ‘hub’ with a precompiled anaconda environment and jupyter notebooks executable on a remote server. Please feel free to take and use these notebooks from the associated github repositories, no permission necessary.
